Definitions

  • This application relates to the field of wireless communication technologies, and in particular, to a polar code-based interleaving method and apparatus.
  • an interleaving operation is performed on a polar code at a transmit end and a de-interleaving operation is performed at a receive end.
  • a function of interleaving is disordering elements in an original data sequence, to weaken a correlation between data sequences before and after interleaving, and reduce impact of a data burst error, thereby improving anti-interference performance.
  • a random interleaving manner is provided. According to the random interleaving manner, when an interleaved sequence is offline calculated, a permutation sequence needs to be recorded for use in interleaving and de-interleaving. When a code length is relatively long, an implementation process of reading a sequence obtained after random interleaving is relatively complex.
  • the interleaving matrix is determined by performing column bit order reversing or row bit order reversing on an initial interleaving matrix.
  • the initial interleaving matrix is determined based on n unit matrices, or the initial interleaving matrix is determined by transposing a matrix obtained after n unit matrices are processed according to a specified algorithm, and n is determined based on the target code length M.
  • the communications apparatus 1400 may be implemented by using a bus 1401 as a general bus architecture. Based on a specific application and an overall design constraint condition of the communications apparatus 1400, the bus 1401 may include any quantity of interconnected buses and bridges. The bus 1401 connects various circuits together. The circuits include a processor 1402, a storage medium 1403, and a bus interface 1404. Optionally, the communications apparatus 1400 is connected to a network adapter 1405 and the like through the bus 1401 by using the bus interface 1404.
  • the network adapter 1405 may be configured to: implement a signal processing function of a physical layer in a wireless communications network, and send and receive a radio frequency signal by using an antenna 1407.
